             Summary: LLAP: NegativeArraySize exception on some vector string reader
                 Key: HIVE-10011
                 URL: https://issues.apache.org/jira/browse/HIVE-10011
             Project: Hive
          Issue Type: Sub-task
            Reporter: Gopal V


With some logging, I confirmed that the String length vectors contained junk data & the
length field is overflowing.
